Description

[Detailed Description of the Invention] The present invention relates to a methane gas generator, and more particularly, to a methane gas generator that ferments organic waste such as kitchen waste and livestock waste to generate methane gas, which is used as fuel.

Most of the conventional generators of this type are made of brick or concrete, which is expensive to construct, and most of them are installed outdoors under the ground, which results in a large amount of heat dissipation, especially in cold regions. During the winter, when it is most needed, the temperature inside the fermentation chamber is much lower than the optimal temperature for fermentation and decomposition, 20-37℃.
In many cases, the temperature is below 10℃, and the generation of methane gas almost stops, or in cases where methane gas can be generated, large amounts of expensive fuel are forced to be used in order to obtain the optimal fermentation and decomposition temperature. There was a drawback.

The present invention has been made with the aim of eliminating all of the problems of the prior art, namely, the present invention is constructed from a flexible rubber or plastic sheet and can be folded as needed. The present invention relates to a methane gas generator comprising a combination of a methane gas generator A that generates methane gas by fermentation of organic waste, and a foldable hanging member B for hanging the generator A while it is housed and supported.

The device of the present invention has a combination structure of a methane gas generator A constructed from a flexible rubber or plastic sheet as described above, and a foldable hanging member B, both of which are mass-produced at a factory. As a result, the manufacturing cost of the device is low, and since the generator A and the hanging member B are both foldable, they can be transported with the minimum capacity, reducing transportation costs.Furthermore, when assembling, the methane gas generator A can be attached to the hanging member. B
All you have to do is hang it in a predetermined location using a holder, and there is almost no assembly cost.

According to the present invention, the total cost required for installing the device is much lower than that of conventional solid devices such as bricks and concrete, and the installation cost can be significantly reduced.

At the initial stage of assembly, generator A may be kept in a folded state, but due to the methane gas generated by charging raw materials into generator A and fermenting the input raw materials, generator A
Since it expands naturally, there is no problem in using it.

Furthermore, in the device of the present invention, the methane gas generator A is constructed from a rubber or plastic sheet, which provides good heat retention and reduces heat dissipation.

Therefore, even in winter in a cold region, for example, methane gas can be effectively generated without consuming valuable fuel, or even if it is consumed, with the consumption amount being minimized.

In particular, the device of this invention is foldable, so it can be dismantled and moved freely.For example, in the winter, it can be brought into an existing building such as a barn or a greenhouse in a folded state, and assembled and used. It also has the advantage of further reducing heat dissipation.

In this case, when the weather gets warmer, you can fold it again and take it outside and hang it in a suitable place.

In the present invention, the methane gas generator A is not particularly limited as long as it has a structure that can ferment organic waste and generate methane gas.

Fig. 1 shows a vertical type generator A, and this vertical type generates organic waste a fed from the input port 1 at the top.
While being digested in the upper digestion chamber 2, the water in the lower fermentation chamber 3 passes through the inclined bottom wall 2a at the bottom of the digestion chamber 2 and the downcomer pipe 2b extending downward from the bottom end of the bottom wall 2a. b) and ferments to generate methane gas.

In this embodiment, methane gas generated in the fermentation chamber 3 is stored in an upper part 3a of the chamber 3 and a gas reservoir 3C connected to the upper part 3a via a conduit 3b.
It is taken out from the take-out pipe 3e provided in the fuel tank and consumed as fuel.

In the figure, 3C' is the weight of the gas reservoir 3c, 4 is the residual fertilizer removal pipe, and 5 is the water circulation pipe. The heated wastewater will be used by incinerating the waste and heating it by consuming a portion of the recovered methane gas as necessary.

3d is a safety device for preventing flame backflow.

An example of a horizontal generator A' is shown in FIGS. 2 and 3,
In this system, the digestion chamber 2' and the fermentation chamber 3' are separated by a partition plate 2C.
The interior of the equal chambers 2' and 3' are
The partition plate 2C is communicated with through a partially shaped opening 2d on one side of the lower part of the partition plate 2C.

In this case, the port 2d is the raw material input port 1' as shown in FIG.
It is preferable to configure the fermentation chamber 3' so that the raw materials are fed into the fermentation chamber 3' in order from the digested raw materials.

In addition, as shown in Fig. 2, the tank part of the generator A' has a flexible hollow double structure, and the methane gas generated in the fermentation chamber 3' is passed through the double structure A'1. Storage part (
(not shown), this methane gas can be used to expand and keep the generator A' warm.

The hanging member B for hanging the methane gas generator A (or A') while storing it is not particularly limited as long as it can be folded. A 7-car type is shown.

The mesh basket 7 is made of, for example, natural fiber yarn or synthetic fiber yarn.

This mesh basket 7 is suspended from, for example, a support beam 8 by a hanger 7a.

In the present invention, the entire methane gas generator A or A' does not necessarily have to be made of a flexible rubber or plastic sheet, and at least the main body of the generator A or A' may be made of such a sheet. It suffices if the sheet is made of suitable sheets.

For example, the piping system may be constructed from hard pipes.

Furthermore, it is preferable that the bottom wall 2a, the downcomer pipe 2b, or the partition 2C of the digestion chamber 2 be made of flexible sheets (including pipes), but in some cases they may be made of relatively hard plastic. good.
